PTZ Issue - could it be a Protocol issue?

[Ernie Douglas 0]

Following on from my original thread regarding system upgrade advice I am having trouble getting my new Qvis Viper DVR to communicate via RS485 to my PTZ cameras.  

The 15-AU50ES joystick, which was connected to the previous DVR does Pan, Tilt and Zoom the cameras so I know they work and that the cables are OK.  The 15-AU50ES supports PELCO-P, PELCO-D and COP-2 protocols.  The DVR does not support COP-2 protocol.  I have been through the list of protocols in the DVR settings and tried all of them but to no avail.  Do I assume then that the camera must be configured to COP-2?

I have read somewhere that cameras support more than one protocol so how do I switch the cameras to use something that the DVR supports?  Is there a physical jumper maybe or is it in the firmware and if so how do I access it?  I dont have a manual for my cameras, they were in the property when we moved in.

In my other thread I was told that the cameras are a sunkwang and a 12inch VCL but google turns up zero results when I look for a manual for either.

Any help would be appreciated.

Thanks

Hi. This will just be a setup problem 

with your ptz cameras view on the screen power them down wait 2mins then back on first thing they will do is go into setup mode ….. you will see your camera moving to set points …. But while it’s doing this you will also see the camera settings on the screen 

address -protocol-baud rate 

then in dvr ptz setup match those settings to the camera ……..

Fabulous Tom, thanks for the tip.  I will do that tomorrow as I have an early (05:30) start in the morning so I am off to bed now.

I will let you know how it goes.

Ernie.

Thanks Tom for the advice on getting camera setup info.  I just took a screen picture with my phone while the cameras were starting up.

Unfortunately, whilst I now know I have the right settings, the PTZ controls in the software still wont work.  I will check and double check all the connections again at the DVR end.  

If I try swapping the  RS485 connections round will that cause any damage?  I ask because I cant remember ever trying the PTZ controls on the old DVR because it was in-situ when we purchased the property and I have never had a need to use then on-screen controls so therefore I dont know if they worked before.

If I move the cameras using the joystick and then try to save that set position in the DVR software it doesn't save anything. 

The alarm inputs work OK because when someone triggers an alarm a pop-up appears on the screen saying so.

I guess I may have to call in a CCTV specialist if swapping the control wires around does nothing.

Thanks,

Ernie.

Hi ….. no you won’t have problems switching rs485 around as it’s only data not power

just for a quick test remove the 485 from keyboard and connect to dvr and see if you have control then

Thanks for the help Tom.  Once I knew I couldn't do any harm I played about with the cable connections and now I seem to have got everything working and I think I have figured out how to programme the settings I need to set in the DVR.

Next on the list will be a camera upgrade and after that I need to add some additional fixed cameras.  I will start a new thread regarding the cameras.
